I was one of the many people affected by the weird bug that made it so non-root users couldn't login. Thanks to the documentation on the Slitaz website I was able to fix it only to end up with another problem.
When I log in as my non root user 'mike' there's no LXpanel at the bottom and no PCManFM drawing the background and desktop icons. All that appears is the white mouse cursor on a black screen. Of course, I can right-click to get the Openbox menu and open two terminals to invoke LXPanel and PCManFM, but they should be loading automatically from my autostart.sh file. What gives?
I checked my /home//.config/slitaz/applications.conf file and it only had "openbox" under WINDOW_MANAGER. Changed it to openbox-session, logged out, and then logged back in and it worked.
So if anyone else has this problem, go to that file and change the last line so it looks like this:
